The plate 50 according to ourinvention and articularly or slide-bar above mentioned passes betweenfixed plates or guides, in each of which is formed a slot, through whichand through a hole in the plate or slide-bar before referred tween thefixed plates above referred to. Se-

cured to or formed upon the arms before mentioned are brackets capableof revolving in and supported by which are shafts, upon which are formedright-hand screw-threads and left-hand screw-threads. The said righthand screw-threads and left hand screwthreads by means of suitable jawscause the brush board or stock to be secured or held while beingoperated upon.

To the frame-work of the machine between the place where the brush boardor stock is placed while being operated upon and the templet abovereferred to we fix ahead-stock, in which is mounted a rotating spindle,which carries the drill employed to form the holes in the brush board orstock to be operated upon. Projecting from a bracket secured to theframe-work of the machine and in front of the templet previouslyreferredto is a projecting stud or pin. In the templet above mentionedwe form holes corresponding in position and arrangement to the holes tobe formed in the brush board or stock to be operated upon. The brushboard or stock to be operated upon is secured to the arms abovementioned by means of the screws and jaws above referred to. Theattendantthen places one of the holes in the templet upon the projectingstud or pin above mentioned and draws or slides the templet along suchstud or pin. The movement of the templet and parts connected theretowill cause the brush board or stock to be operated upon by the drill,the depth of the hole drilled being regulated by a stop. The templetabove mentioned may contain as many holes as are to be formed or drilledin the brush board or stock, or the templet may only contain holescorresponding'in position and arrangement to a portion of the holes tobe formed in the brush board or stock, the remaining holes in the brushboard or stock being formed by a subsequent operation.

The tufts of bristles, fiber, bass, or other material of which the brushor broom is composed we shall for convenience hereinafter re-' fer to asthe tufts of bristles.

In the accompanying drawings, Fig. l is a plan and Fig. 2 a side view ofone of the machines constructed according to our invention.

According to the first part of our invention we employ a templet a,secured to arms a, which are capable of being moved longitudinallythrough sockets 1), formed in a bar I), hinged or jointed by a rod 0 toa plate or slidebar d, in which are formed holes (1', in any one ofwhich a pin or stud e may be placed.

The arms a may be secured in any desired position in the sockets Z) mymeans of setscrews 1) or equivalents therefor.

The arms a and bar I) form a frame, which carries the templet a andclamp h or other clamping device, to be hereinafter described,constituting a holder for the brush board or stock. The plate orslide-bar 6. passes between fixed plates or guidesf, in each of which isformed a slot f, through which and through one of the holes 61' ispassed the pin or stud e. The plates or guides fact as guides to preventthe plate or slide-bar d from rotating and leave such plate or slide-bard at liberty to be turned horizontally upon the pin or stud 6 while theplate or slide-bar d is being moved longitudinally between the plates orguides f. The plates or guides fare secured together by means of thescrews f which pass through washers or thiinblesf 'by which the platesor guidesf are prevented from binding upon the plate or slide-bar d.

Secured to or formed upon the arms a are brackets a carried by which andcapable of being revolved therein are shafts 9, upon each of which areformed right-hand screwthreads 9' and left-hand screw-threads g Mountedupon the shafts g and acted upon by the screw-threads g g are jaws h,which may vary in form and size, according to the shape of the board tobe held by them. The

shafts g are geared together by means of wheels g so that when one ofthe shafts g is turned by means of the handle g the other shaft 9 willalso be turned. The brush board or stock to be operated upon is placedbetween the jaws h, and the handle 9 being turned the screw-threads gwill cause the said brush board or stock to between the jaws h. Theright-hand screwthreads 9' and left-hand screw-threads 9 cause eachbrush board or stock being operated upon to be held midway between thearms a, although the brush boards or stocks may not be of a uniformlength. I

To the frame-work or bedjof the machine and between the brush-board orstock being operated upon and the templet Ct we fix a head-stock 70, inwhich is mounted a rotating spindle l, which carries the drill m,employed to form the holes in the brush to be operated upon.

Projecting from a bracket 92, secured to the frame-workj of the machineand in front of the templet a, is a projecting pin or stud 0.

board or stock be firmly held 7 In the templet a we form holes A, asshown in Fig. 3, which is a. The holes A correspond in position andarrangement to the holes to be formed or drilled in the brush board orstock to be operated upon. The brush board or stock to be operated uponis secured to the arms a by means of the shafts g and jaws h. Theprojecting pin or stud 0 is so adjusted by the nuts 0 and screw-threadsthat when one of the holes A, formed through the templet a, is placedupon the projecting pin or stud o and a front View of the templet 'e isplaced slid longitudinally thereon in the direction indicated by thearrow B such pin or stud 0 will act as a guide and support for thetemplet a.

m, is a stop formed with the shank m which passes through a hole formedin the head-stock k and may be secured therein by means of aset-screw mThe stop m is so adjusted relatively to the point of the drill'm thebrush board or stock to be operated upon.

by the drill m, the depth of the hole formed in the brush board or stockbeing regulated by the stop m. The attendant repeats the above-describedoperation until the desired number of holes has been drilled in thebrush board or stock, and then, turning the handle 9, releases the brushboard or stock and replaces it by another to be operated upon.

The templet a may contain as many holes A as are to be formed or drilledin the brush board or stock, or the templet a may only contain holes,corresponding in'position and arrangement to a portion of the holes tobe formed in the brush board or stock, the remaining holes in the brushboard or stock being formed by a subsequent operation. The slots f allowthe templet a and parts connected therewith to be moved in the directionof the length of the machine.

The templet a, arms a, jaws h, and the brush board or stock beingoperated upon can be turned upon the rod 0, as indicated by the dottedlines in 2. The movement of the arms a upon the pin or stud e and uponthe rod 0 will cause the holes drilled in the brush board or stock to bedrilled at an angle, in order that the required spread may be given tothe bristles or other fiber or material subsequently inserted in theholes formed in the brush board or stock. WVhen the pin or stud in ahole 61' farther away from the templet a, the holes drilled in the brushboard or stock will be drilled more nearly parallel to each other thanwhen the pin or stud e is placed in a holed nearer to the templet a. Bythe set-screws 19 being slackened and the templet a and jaws 7'L beingadjusted in position so as to be farther from the axis of the rod 0 theholes drilled in the brush board or stock will be drilled more nearlyparallel to each other in planes at right angles to the rod 0 than whenthe templet a and jaws h are placed nearer to the axis of the rod 0. Bythe templet a and jaws h being adjusted in position so as to be nearerto or farther from the axis of the rod 0 and the pin or stud 9 beingplaced in one or other of the holes 01', holes may be caused to be sodrilled or formed in the brush board or stock as to give a greater orless amount of spread to the bristles, bass, or other fiber forming thebrush or broom, as may be desired.

The machine illustrated by Figs. 1 and 2 is intended to be employed fordrilling brush boards or stocks in which the holes require to have onlya small degree of angle or divergence.

Figs. 1, 1 and 1 show the form of brush board .or stock inrthedrillingof the holes in which the machine shown in Figs. 1 and 2 isrequired.

Indrilling or formingthe holes in brush boards or stocks of a roundedorcurved form we secure the brush board or stock to be op-. erated uponbetween jaws, which may be placed at an angle or rotated, or we mountthe brush board or stock between supports, one or both of which may beplaced at an angle or rotated. We cause the amount of turning orrotation imparted to the brush board or stock to be determined by meansof a dividing disk or plate provided with a suitable catch, by means ofwhich the dividing disk or plate or brush board or stock is preventedfrom being turned except when required. By the brush board or stockbeing placed nearer to or farther from thetemplet or bythe pinabovementioned which slides in the slot above referred to being placednearer to or farther from the brush board or stookthe angle ordivergence of the holes may be made greater or less, as may be desired.A machine arranged for performing this portion of our invention isillustrated by Figs. 4 and 5 of the accompanying drawings. As certainparts of the machine illustrated by Figs. t and 5 are similar inconstruction and operation to some of the parts shown in Figs. 1 and 2,we shall apply to such parts the same letters and figures of referenceas are applied to the corresponding parts in Figs. 1 and 2. The machineillustrated in Figs. 4 and 5 is especially arranged for drilling theholes to receive the bristles, fiber, bass, or other material of whichthe brush or broom is formed in circular or cylindrical brushes orbrooms, in which the surface in which the bristles, fiber bass, or othermaterial are or is secured is circular or of a circular section. Securedto the plate or slide-bar d are brackets p p. Carried by the bracket 10and capable of being rotated therein is a spindle r'. Fast upon thespindle r is a cup 1", having projecting from its surface pins orspikes. Fast upon the spindle r is a toothed wheel r Secured to thebracket p is a stud p and mounted upon such stud p is a click or catch pThe wheel r and click or catch p3 constitute a dividing apparatus. Fastupon the spindle r is a handle W, by which the spindle r may be turned.Carried by and free to be turned in the bracket 19 is a screwed spindles, which is provided with a handle 8, by means of which the spindle 8may be turned. The spindle sis formed with a conical point 8 The brushboard or stock to be operated IIO the cup 1' is provided.

upon is placed between the cup 1" and the point 8 The screwed spindlesis then turned by means of the handle 8', so that the brush board orstock will be firmly held between the point 8 and the pins or spikeswith which The cup 0" assists in holding the brush board orstock in thetrue position for being operated upon. Through the templet a. are formedholes A corresponding in arrangement with the holes to be drilled in thebrush board or stock to be operated upon. After one row of holesextending in the direction of the length of the brush board or stock hasbeen drilled the click or catch 19 is raised clear of the teeth of thewheel r and the spindle r and brush board or-stock are turned by meansof the handle r through the angular distance necessary to bring thebrush board or stock into the required position for having another rowof holes formed therein. When the brush board or stock has been turnedto the desired position, it is retained therein by the click or catch pIn those cases in which the machine is to be employed for drilling theholes in brush boards or stocks of a semicircular. section, such as isshown in Fig. 6, the brush boards or stocks may be secured together backto back in pairs, as shown in Fig. 7, so

that two of such semicircular brush boards or stocks may be drilled asone circular brush, in which form they are drilled more readily andcheaply than they would be separately.

According to another arrangement of our invention we employ a frame andtemplet similar to that above mentioned, which frame is provided with across-bar, which is capable of being moved upon a fiat bar in which areformed a number of holes. The cross-bar and the fiat bar above mentionedare secured together by means of a pin,which passes through a hole inthe cross-bar and one of the holes formed in the fiat bar abovementioned. The flat bar above mentioned is jointed or hinged to a bar orplate capable of being slid longitudinally between guides secured to theframe work of the machine. A machine constructed according to thisarrangement of our invention is shown in Figs. 8 and 9 of theaccompanying drawings. Fig. 8 is an elevation, and Fig. 9 a plan, of amachine constructed according to our invention and particularly adaptedfor drilling the end holes of certain brushboards or stocks, which holesrequire to be drilledat a considerable angle to the other holes drilledin the brush board or stock and also require to have a considerableamount of angle, divergence, or spread. Figs. 8, 8 and 8 serve toindicate the class of holes in the drilling of which the machine shownin Figs. 8

4 and 5. The arms a carrvin the 7 9 a and 9 is required. To such of theparts shown in Figs. 8 and 9 as correspond to parts shown in Figs. 1, 2,4, and 5 we shall apply the same letters and figures of reference as areapplied to the corresponding parts in Figs. 1, 2, templet a, passthrough sockets 1), formed upon a bar or frame 19*, capable of beingturned horizontally upon a flat bar or plate 01 to which the bar orframe b is jointed by means of a pin 6 which is passed through one of aseries of holes d, formed in the flat. bar or plate (1 The flat bar orplate d is jointed or hinged by means of a rod 0 to a bar or plate 01,capable of being slid longitudinally between ends of the bar '0 passthrough curved slots 11 formed in parts, each formed on one of the armsa. The bar 11 is provided with nuts v by means of which its ends may besecured in any desired position in the slots v The nuts n beingslackened, the jaws h* and bar 0 are turned aroundthe shaft 71/ untilthe jaws 71* are in the position for presenting the brush board or stockto be operated upon in the required position to the drill m. The bar 1)is then secured in the slots 0 by means of the nuts v The face of thetemplet a, is placed at an angle to the bar 12 and parallel, or nearlyso, to the portion of the brush board or stock in which holes are to bedrilled. By

the pin 5 upon which the bar or frame 12 turns, and placing the rod c,bywhich the fiat bar or plate 01 is hinged or jointed to the bar orplate 1) near to the'pin 19 we are enabled to obtain the divergence orspread of the holes which is necessary to give the required degree ofdivergence or spread to the tufts of bristles placed in the extremity orextremities of certain kinds of brushes or brooms such, for instance, asstove-brushes, scrubbing-brushes, and brooms.

- A further portion of our invention consists in apparatus by means ofwhich we are e'n abled to bore or drill the brush boards or stocks inwhich it is desired that the holes bored or drilled in such brush boardsor stocks shall have a considerable amount of angle or divergence. Inthe frame'or arm to which the templet previously referred to is securedwe mount a bar or shaft, a portion of which is formed with a hollow orcavity, in which the brush board or stock to be drilled or bored isplaced and secured thereto by means of a screw and suitable clamps andjaws. Fast upon the bar or shaft is mounted a toothed sector, the teethof which gear into the teeth .of a toothed sector mounted fast upon theslide or bar upon which turns the arm or frame to which is secured thetemplet and the brush board or stock to be operated upon. When the armor 'frame is moved into the position required when drilling the holesalong the sides of the brush board or stock, such moving of the arm orframe will by means of the toothed sectors cause the shaft or bar to.mounting the jaws h* over or nearly over ICC ITO

which the brush board or stock is secured to ploying toothed sectors ofsuitable radius.

Figs 10 and 11 show a machine constructed according to this portion ofour invention. Figs. 10, 10 and 10 show the form of brush board or stockin the drilling of the holes in which the machine shown in Figs. 10 and11 'is required. As parts of the machine shown in Figs. 10 and 11 aresimilar in construction and operation to parts of machines hereinbeforedescribed, we shall apply to such parts the same letters and figures ofreference as have been applied to the corresponding parts hereinbeforedescribed and shall not describe such partsfurther than maybenecessaryin describing the construction and operation of the other partsused in conjunction therewith. Upon the arms a, to which is secured thetemplet a, are formed bosses w, passing through which and capable ofbeing turned therein is a shaft 0:, upon which shaft 00 are formed orsecured brackets 00'. Carried by the brackets x and capable of beingrotated therein are shafts g, upon which are formed right-handscrewthreads g and left-hand screw-threads 9 Upon the screw-threads g gand acted upon thereby are jaws or clamps It. Fast upon one end of eachof the shafts g is a toothed wheel g which gears into a wheel 9 mountedso as to be'free to turn on the shaft m. Fast upon one of the shafts gis a handle 9 By thesaid shaft 9 being turned by means of the handle g?motion will by means of the wheels 9 9 g be transmitted to the othershaft 9 and the .jaws or clamps it may be caused to approach toward orrecede from each other. Fast with the plate or slide-bar d are arms (1mounted upon which and free to turn thereon are steps at. In the arms aare formed-slots a in which are situate the steps d upon which the slotsa may at times be slid by means of screws a passing through the arms a.Fast upon the-arms d are wheels y, which gear into wheels m fast uponthe shaft ac. When the templet a and arms a. are turned upon the arms dthe wheels 00 shaft m, and brackets at will be turned through a portionof a revolution around the axis of the shaft :0, sothat the holesdrilled in the brush board or stock will be caused to have aconsiderable angle or divergence The divergence of the holes drilled orbored in the brush board or stock may be increased or diminished byemploying toothed wheels x 'y of suitable diameter, the arms (1 beingadjusted in relation to the shaft cc as may be necessitated by thediameters of the wheels or 'y, placed upon the shaft m and arms (F. Forconvenience of construction weplace toothed wheelssuch as 00 y-upon theshaft to and arms (1 the operative portions of such wheels constitutingtoothedsectors; but, if desired, toothed sectors may be employed inplace of the toothed wheels m y.

Fig. 12 is a plan, and Fig. 13 an elevation, of another arrangement ofmachine constructed according to this portion of our invention. In Figs.12 and 13 to parts corresponding to those above described are appliedthe same letters of reference as are applied to the corresponding partsabovedescribed. d is a plate or slide-bar capableof being slid betweenthe fixed plates f. Edgewise through the plate or slide-bar d is formeda slot (1 situate in which and capable of being turned horizontallytherein is a plate or bar .2. Through the plate or slide-bar d areformed holes, in any one of which isplaced a pin 1, capable of'beingslid in a slot f formed in one of the fixed plates f. Through the plateor bar z are formed holes, in any one of whicha pin 2' maybe placed.Formed upon the'plate or bar 2 are arms 2 upon which are formedprojecting parts, through which are screwed set-screws 2, the ends of"which form pivots upon which the arms a may be turned. To the arms a issecured the templet a. Carried by the arms a, and capable of beingturned therein are short spindles 3, in each of which is formed'a box 4,into which passes one end of a stud 5, projecting from a bracket 6.Carried by the brackets 6 andcapable of being turned therein are shafts9, upon each of which are formed right-hand screw-threads g andleft-hand screw-threads g Mounted upon and acted upon by thescrew-threads g g arejaws h.

Fast upon each of the shafts g is a wheel 9 which gears into a wheel 9mounted loose upon one of the studs 5. 'By means of the handle g fastupon one of the shafts g, the shafts g may be turned. Fast upon each ofthe spindles 3 is an arm 7, in which is formed a slot. Upon the arms aare formed bosses 8, through each of which passes a rod 9. Upon each ofthe rods 9 are formed screw-threads. The rods 9 are capable of beingadjusted longitudinally in the bosses 8, and after adj ustment may besecured in position by means of nuts 9. Each of the rods 9 is providedwith a pivot 10, which projects into the slot formed in one of the arms'7, fast upon one of the spindles 3. When the arms Ct and templet Ct areturned upward or downward upon the pivots formed by the set-screws 2,the movement of the arms a and templet a, will cause one side or theother of the slot in each of the arms 7 to arrive against the pivot 10,projecting into such slot, and thereby cause the spindles 3 to beturned. By adjusting the rods 9 by means of the nuts 9 so' that thestuds 10 are nearer to or farther from'the axes of the spindles 3 thespindles 3 may be caused to be turned in a greater or less degree by agiven movement of the armsa and templet a and the divergenceof the holesdrilled in the brush-board or stock across the width of the brush boardor stock may be made greater or less, as may be desired.

Fig. 14 is a view of certain parts illustrating the manner-in which theposition of the brush board or stock is changed by the templet a beingdepressed.

The arrangement of machine shown by Figs. 12 and 13 is particularlyapplicable for drilling the holes in brush boards or stocks having theform shown in the detached View Fig. 15. This is the example of ourinvention to which we attach most importance. When the holes in theportion of the brush board or stock between the points 13 and O arebeing drilled, the arms 2 are fixed to the plate or slide-bar cl by thepin z and a pin 2 passed through one of the holes in the plate orslidebar d, the plate or slide-bar 02 being then free to move upon thepin 1, situate in the slot f and one of the holes formed in the plate orslide-bar d. WVhen the holes in the portion of the brush board or stockbetween the points 0 and D are to be drilled, another pin 1 is passedthrough the slot f and into one of the holes formed in the plate orslide-bar 61, so that the plate or slide-bardcan only be moved in thedirection of its length, and the plate or bar .2 is secured to the plateor slide-bar cl by means of one pin 2', passed through one of the holesin the plate or slide-bar d and one of the holes in the plate or bar 2,the pin 2 being removed. 7

By the arrangement of machine shown in Figs. 12 and 13 we are enabled todrill the holes in a brush board or stock so that the holes in oneportion of the brush board or stock will have a greater or less degreeof divergence than the holes in another portion of the brush board orstock.

Fig. 16 shows one method of holding in posi tion while being drilledbrush boards or stocks of a form such as that shown atE and of formssimilar thereto. To bars ,h**, which are caused to approach toward orrecede from each other by the right-hand screwthreads g and left-handscrew-threads 9 we secure plates h, which plates h, in conjunction Withthe bars h**, form angular recesses 71. as shown in Fig. 17, whichangular recesses 71*, when the bars h** are caused to approach eachother, retain the brush board or stock to be operated upon in positionwhile being drilled. The plates 77. are formed so that they willsecurely hold the brush board or stock to be operated upon While suchbrush board or stock is being drilled.

According to a further part of our invention we employ a frame providedwith a templet, as above described. In one end of each of the arms ofsuch frame are formed holes, which are passed upon a bar or rod or barsor rods formed upon or secured to a plate or bar capable of being slidlongitudinally bebars or rods before mentioned and may also be slidlongitudinally upon the said bar or rod or bars or rods. Thisarrangement of our invention is particularly applicable to brush boardsor stocks in which the rows across the width have a slight amount ofangle or divergenceand in which the rows lengthwise of the brush boardsor stocks are parallel. A machine constructed according to this part ofour invention is illustrated by Figs. 18 and 19 of the accompanyingdrawings. Figs. 18* and 18 show the form of brush board or stock in thedrilling of the holes in which the machine shown in Figs. 18 and 19 isrequired. As certain parts of the machine illustrated by Figs. 18 and 19are similar in construction and operation to similar parts employed inthe machines previously referred to, we shall affix to such parts thesame letters and figures of reference as We have applied to thecorresponding parts above described. Secured to the slide-bar or plate dis a rod 0*. The arms a. are provided with sockets 17, which are capableof being turned and slid longitudinally upon the rod 0*. Secured to thearms a is the templet a, which in the machine now being described isstraight. The brush board or stock to be operated upon is fastened tobrackets 18, secured to or formed upon the arms a. As the movement ofthe templet a. in the direction of the axis of the rod 0* and themovement in the same direction of the brush board or stock beingoperated upon are equal, the holes in each horizontal row of holesdrilled in the brush board or stock will be the same distance apart asthe corresponding holes A* in the templet a; but the horizontal rows ofholes drilled in the brush board or stock may be caused to be nearertogether or farther apart, according as the brush board or stock isplaced farther from or nearer to the axis of the rod 0*. The turning ofthe arms or upon the rod 0* will cause the rows of holes across thewidth of the brush board or stock to have a slight amount of angle ordivergence. We have for convenience of illustration-shown the arms a andtemplet a as broken. The templet a will require to be of sufficientlength and breadth to contain as many holes as are to be drilled orformed in the brush board or stock to be operated upon. The arms a willrequire to be of such length that the templet a and the brush board orstock may be placed at such a distance from the axis of the rod 0* thatthe holes forming the vertical rows of holes drilled or formed in thebrush board orstock will have only a small amount of angle or divergencein a direction at right angles to the length of the brush board orstock.

By means of our invention we are enabled to employ one templet in thedrilling of brush boards or stocks of various sizes and in the drillingof holes of various sizes.
